The scope of the digital 3C industry is quite broad. The computer aspect includes notebook computers, various computer hardware and various peripheral equipment, and the communication aspect includes wireless communication equipment, user terminal equipment, switching equipment, and transmission equipment. The mobile phone and telecommunications industries are the main axis. Consumer electronics include mobile phones, digital cameras, tablet computers, electronic dictionaries and other digital products. They are all consumer electronics products. The 3C industry has a short life cycle, and continues to reduce costs and flexibility. The 3C industry has gradually developed into a world-wide emerging technology industry, riding on the pace of the digital age.
As a pivotal part of the technology industry, the rapid update of mobile phone manufacturing has continuously challenged the technological capabilities of many businesses. Limited mobile phone space requires more antennas. After 4G is up, operators require 5-mode ten-band, new phones need to be compatible with 3G and 2G, and MIMO requires two antennas. This makes the types of antennas in mobile phones more diverse and the electromagnetic environment deteriorates, especially the area of metal parts on the appearance of mobile phones. Later, how antenna engineers and structural engineers can debug smart phones that meet the network access requirements encountered unprecedented challenges.
As 3C products are becoming smaller and more sophisticated, the requirements for welding technology are getting higher and higher. This is especially true for the mobile phone industry, which is one of the main forces of 3C. The radio frequency antenna used in mobile phone manufacturing is also becoming more and more complex, as the laser micro welding industry. Pioneer, because the mobile phone copper foil laser welding has the characteristics of high energy, high precision, high directionality, and the original PID temperature feedback system can effectively control the processing environment at a constant temperature, avoiding damage to the product due to excessive processing temperature, greatly Improve the yield rate of processing, efficiently solve the welding difficulties of radio frequency antennas, and provide strong processing support for the development of my country’s 3C products toward precision.
The radio frequency antenna in the mobile phone radio frequency identification is RFID (Radio Frequency IDentification) technology, also known as electronic tags, radio frequency identification, is a communication technology that can identify specific targets and read and write related data through radio signals without the need for identification systems and specific Establish mechanical or optical contact between targets. Due to the particularity of the radio frequency antenna, the welding of the coaxial cable has higher requirements, and the welding method of the laser welding system is the best choice for the welding of the radio frequency antenna of the mobile phone.
